Comprehensive atrial fibrillation package of care to minimise unnecessary hospital admission and improve patient outcome: a quality improvement project

Abstract Funding Acknowledgements None. Introduction Recent studies have highlighted an increasing rate of hospitalisation among atrial fibrillation (AF) patients, despite a relatively low in-hospital mortality rate. This trend carries significant financial implications, with a twofold increase in AF-related expenditures, over 50% of which are associated with inpatient care. Purpose A Quality Improvement Project (QIP) was conducted to enhance AF care, reduce unnecessary admissions, and address the root causes driving increased hospitalisations. Methods The root cause analysis, illustrated in Figure 1, revealed four factors contributing to the increased hospital admission rate of newly diagnosed AF patients: systemic issues, the nature of the disease itself, patient and physician-related factors. The driver diagram (Figure 2) visually presented the primary and secondary drivers with corresponding interventions targeting potential areas for improvement. Plan, Do, Study, Act (PDSA) cycle was conducted using four-pronged approach: 1. Updating local guidelines and designing a stepwise algorithm to align with contemporary standards of care. 2. Establishing an ambulatory care/arrhythmia clinic referral pathway for follow-up of stable AF patients to ensure continuity of care, thus minimizing unnecessary admissions. 3. Implementing a safe discharge toolkit comprising patient education materials, a poster for stroke and bleeding risk assessment tools, and an anticoagulation checklist. 4. Incorporating AF management teaching sessions into the doctors’ induction curriculum to enhance their knowledge and confidence in managing newly diagnosed AF patients and ensuring safe discharges. Results Lack of an ambulatory care or arrhythmia clinic referral pathway, inadequate educational resources, insufficient clinician training were key factors contributing to unwarranted hospitalization of newly diagnosed AF patients. The comprehensive guideline revision process, requiring substantial resources and the support of stakeholders and a multidisciplinary team comprising cardiologists and emergency and acute medical physicians, facilitated the successful implementation of the new AF referral pathway. This QIP resulted in a 16% reduction in avoidable admissions, 24% increase in clinician confidence, and 18% improvement in adherence to stroke and bleeding risk assessment protocols, in addition to reducing the hospital stay duration. Conclusions The collaboration among diverse medical disciplines, evidence-based guideline revision, and the implementation of a streamlined AF referral pathway demonstrated the potential to reduce healthcare resource utilization and financial burdens. This approach aligns with national standards, enhances healthcare providers' knowledge and confidence, ensuring standardised clinical practices. It underscores its potential for implementation of similar pathways to improve patient care. Continuous evaluation to evolving guidelines are recommended for sustainability.Figure 1.Ishikawa fishbone diagramFigure 2.Driver diagram for AF care

P198 Systematic review to highlight practices and programmes for transition for adolescents with Inflammatory bowel disease

Abstract Background Adolescents with inflammatory bowel disease (IBD) will eventually transition from the family-centric paediatric healthcare team to the adult service. This process happens at an appropriate age or level of development and depends on a number of factors such as transition readiness, disease specific factors, and local policies and practice. This transition period is challenging for patients, families and healthcare providers. The use of structured transition programmes is increasingly incorporated into standards of care, yet the optimal format is not yet fully delineated, and practices vary considerably. The aim of this study was to carry out a systematic review of structured transition programmes and their components to assess impact on disease-specific and transition-related outcomes. Methods A literature review was carried out in four main databases (PubMed, CINAHL, CENTRAL, EMBASE) and relevant publications from the year range 1970-2023 reviewed. Inclusion criteria: reporting on adolescent IBD patients and investigating structured transition programmes/interventions. Exclusion criteria: not reporting outcomes relating to transition readiness/skills or disease related outcomes. Two investigators reviewed the articles, extracted data, and two assessed bias. Results There were 3432 articles identified from initial searches, and 38 included in the final review. Twenty-six studies reported the use of structured transition programmes, and 12 investigated discrete interventions. The key outcomes studies included knowledge, self-efficacy, adherence, clinic attendance and transition readiness. These outcomes consistently improved with the use of structured transition programmes. Those adolescents with IBD transitioning with no structured programme experienced a 3.5-fold increase in IBD related surgical rates, and 2-fold increase in hospital admission rates. Structured transition programmes were shown to significantly improve transition readiness assessment scores. Transitional care programmes consistently improved the following outcomes; relapse/admission rates, corticosteroid use, quality of life, and surgery. The bias assessment showed between-study heterogeneity, low quality of evidence, and high risk of bias. Conclusion Transition outcomes for adolescents with IBD were consistently improved with the use of structured transition programmes. This literature review highlights the considerable variation in delivery of transition care, and the need for optimization of strategies. There is no current standardized model for adolescent IBD patients in Australasia, and this review will guide development of regional IBD transitional care consensus statements.

Early-Life Exposure to Traffic-Related Air Pollutants Induced Anxiety-like Behaviors in Rats via Neurotransmitters and Neurotrophic Factors.

Recent epidemiological studies have reported significantly increasing hospital admission rates for mental disorders such as anxiety and depression, not only in adults but also in children and adolescents, indicating more research is needed for evaluation of the etiology and possible reduction and prevention of these disorders. The aim of the present study was to examine the associations between perinatal exposure to traffic-related air pollutants and anxiety-like behaviors and alterations in neurological and immunological markers in adulthood using a rat model. Sprague Dawley pregnant rats were exposed to clean air (control), diesel exhaust (DE) 101 ± 9 μg/m3 or diesel exhaust origin secondary organic aerosol (DE-SOA) 118 ± 23 μg/m3 from gestational day 14 to postnatal day 21. Anxiety-related behavioral tests including open field tests, elevated plus maze, light/dark transition tests and novelty-induced hypophagia were performed on 10-week-old rats. The hippocampal expression of neurotransmitters, neurotrophic factors, and inflammatory molecular markers was examined by real-time RT-PCR. Anxiety-like behaviors were observed in both male and female rat offspring exposed to DE or DE-SOA. Moreover, serotonin receptor (5HT1A), dopamine receptor (Drd2), brain-derived neurotrophic factor and vascular endothelial growth factor A mRNAs were significantly decreased, whereas interleukin-1β, cyclooxygenase-2, heme oxygenase-1 mRNAs and microglial activation were significantly increased in both male and female rats. These findings indicate that brain developmental period exposure to traffic-related air pollutants may induce anxiety-like behaviors via modulation of neurotransmitters, neurotrophic factors, and immunological molecular markers, triggering neuroinflammation and microglia activation in rats.

Trends in Hospital Admissions for Mental, Behavioural and Neurodevelopmental Disorders in England and Wales between 1999 and 2019: An Ecological Study.

To investigate the trends in hospital admissions for mental, behavioural and neurodevelopmental disorders (MBNDs) in England and Wales. This is an ecological study using the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. Hospital admission data was collected for the period between April 1999 and March 2019. The most common type of hospital admission was for mental and behavioural disorders due to psychoactive substance use, which accounted for 26.6%. The admission rate among males increased by 8.1% [from 479.59 (95% CI 476.90-482.27) in 1999 to 518.30 (95% CI 515.71-520.90) in 2019 per 1000 persons; p < 0.001]. The admission rate among females increased by 0.3% [from 451.45 (95% CI 448.91-453.99) in 1999 to 452.77 (95% CI 450.37-455.17) in 2019 per 1000 persons; p = 0.547]. The 15-59 years' age group accounted for 65.1% of the entire number of such hospital admissions, followed by the 75 years and above age group, with 19.0%. Conclusion: We observed an obvious variation in MBNDs influenced by age and gender. Observational studies are needed to identify other factors associated with increased hospital admission rates related to MBNDs, specifically among the young population (aged 15-59 years) and males.

Management and Outcomes of Salmonella Gastroenteritis in the Era of Rapid Molecular Testing.

Molecular diagnostics provide a rapid and sensitive diagnosis of gastroenteritis compared with a stool culture. In this study, we seek to describe the changes in medical management and outcomes of children with Salmonella gastroenteritis as our hospital system adopted molecular diagnostics. This study is a retrospective chart review of children <18 years of age diagnosed with nontyphoidal Salmonella gastroenteritis between 2008 and 2018 at a large pediatric health care system in the southeastern United States. Those with immunocompromising conditions and hemoglobinopathies were excluded. Patients diagnosed via molecular testing were compared with those diagnosed solely by stool culture for aspects of management including admission rates, blood culture obtainment, and antibiotic administration. Of 965 eligible patients with Salmonella gastroenteritis, 264 (27%) had a stool molecular test and 701 (73%) only had a stool culture performed. Groups were similar in age and presentation. Those diagnosed by molecular methods had higher hospitalization rates (69% vs 50%, P <.001), more blood cultures obtained (54% vs 44%, P <.01), and received more antibiotics (49% vs 34%, P <.001) despite statistically similar rates of bacteremia (11% vs 19%, P = .05). The rapid diagnosis of Salmonella gastroenteritis by molecular methods was associated with increased hospital admission rates, blood culture obtainment, and antibiotic use. This suggests possible overmedicalization of uncomplicated Salmonella gastroenteritis, and clinicians should remain cognizant of the possibility of providing low-value care for uncomplicated disease.

S1268 Increased Hospital Admission Rates From Alcohol-Related Liver Disease Did Not Impact Mortality During the COVID Pandemic

Introduction: Alcohol related liver disease (ALD) is associated with high mortality, accounting for 48% of cirrhosis-related deaths in the US. Studies show excessive alcohol intake has increased by 21% in the US since the COVID pandemic. Our study aims to compare pre-COVID to pandemic hospitalization and mortality rates to assess the burden of COVID on ALD. Methods: This was a retrospective, IRB approved, study of patients admitted for ALD from January 2019-December 2021. ALD included diagnosis of alcohol cirrhosis, alcohol hepatitis, alcohol fatty liver disease, and acute on chronic liver failure due to alcohol. Pre-COVID admissions ranged January 2019-February 2020 and pandemic ranged March 2020-December 2021. The 30-day mortality was defined as patient death date 30 days or less from admission. The change in ALD admissions through time was analyzed with a local polynomial regression smoothing function plot comparing the average number of monthly pre-COVID ALD admissions to each monthly number of pandemic ALD admissions, and the differences were compared using t-test. Univariate and multivariate analysis with Cox proportional hazards regression model was performed. Pre-COVID and pandemic 30-day mortality rates were compared with Kaplan-Meier survival curve, using a 95% confidence interval. R (version 3.6.2; Vienna, Austria) was used for analyses and p-value< 0.05 was considered statistically significant. Results: Among 688 ALD admissions, 249 were pre-COVID and 439 were pandemic. Pre-COVID and pandemic patients were similar with males (62% vs 61%), average age (56 vs 55), prior diagnosis of cirrhosis (37% vs 33%, p=0.41) and/or alcohol hepatitis (70% vs 65%, p=0.29), respectively. The average number of monthly ALD admissions pre-COVID was 18. During the pandemic, the number of monthly ALD admissions increased to 23 (range 20-26) after restrictions were first enforced, from May-September 2020, then again increased to 26 (range 20-35) after Omicron restrictions were re-enforced, from December 2020-August 2021 (Table). The 30-day mortality rate between pre-COVID and the pandemic was not significantly different by univariate (HR 1.21, CI 0.67-1.88, p=0.67) or multivariate analysis (HR 1.54, CI 0.90-2.64, p=0.11) (Figure). Conclusion: This study demonstrates a significant increase in the number of ALD admissions during the pandemic, particularly following enforcement of public health restrictions. Despite this increase, the 30-day mortality rate has not been impacted.

Association between acute care collaborations and health care utilization as compared to stand-alone facilities in the Netherlands: a quasi-experimental study.

Health systems invest in coordination and collaboration between emergency departments (ED) and after-hours primary care providers (AHPCs) to alleviate pressure on the acute care chain. There are substantial gaps in the existing evidence, limited in sample size, follow-up care, and costs. We assess whether acute care collaborations (ACCs) are associated with decreased ED utilization, hospital admission rates, and lower costs per patient journey, compared with stand-alone facilities. The design is a quasi-experimental study using claims data. The study included 610 845 patients in the Netherlands (2017). Patient visits in ACCs were compared to stand-alone EDs and AHPCs. The number of comorbidities was similar in both groups. Multiple logistic and gamma regressions were used to determine whether patient visits to ACCs were negatively associated with ED utilization, hospital admission rates, and costs. Logistic regression analysis did not find an association between patients visiting ACCs and ED utilization compared to patients visiting stand-alone facilities [odds ratio (OR), 1.01; 95% confidence interval (CI), 1.00-1.03]. However, patients in ACCs were associated with an increase in hospital admissions (OR, 1.07; 95% CI, 1.04-1.09). ACCs were associated with higher total costs incurred during the patient journey (OR, 1.02; 95% CI, 1.01-1.03). Collaboration between EDs and AHPCs was not associated with ED utilization, but was associated with increased hospital admission rates, and higher costs. These collaborations do not seem to improve health systems' financial sustainability.

Increase in admission rates and symptom severity of childhood and adolescent anorexia nervosa in Europe during the COVID-19 pandemic: data from specialized eating disorder units in different European countries

BackgroundThe COVID-19 pandemic, associated with confinement and social isolation, seems to have impacted the course of many mental disorders in children and adolescents. An increase in hospital admission rates for juvenile anorexia nervosa (AN) has been documented in many regions of the world. However, data from Europe are scarce.MethodsWe asked clinicians in specialized eating disorder units in hospitals of maximum care in France, Germany, Italy, Spain, Sweden, and the Netherlands to report on (i) overall (inpatient and outpatient) and (ii) inpatient admission rates for adolescents with AN during 2019 and 2020. Additionally, a modified version of the COVID Isolation Eating Scale (CIES) was used to assess the child and adolescent psychiatrists’ estimations of a possible increase in symptom severity in children and adolescents with AN during the COVID-19 pandemic and to (iii) inquire about the contributing factors perceived by the caring professionals.ResultsFour out of six representatives of European hospitals described a higher rate of overall admissions during the pandemic. Three hospitals out of six reported an increase in inpatient admissions, and two centres had constant high numbers of admissions of both outpatients and inpatients. The clinicians perceived a higher symptom severity in 2020 than in 2019, especially involving more frequent use of social media, longer duration of exercising, and more restrictive eating. They supposed an increase in social media consumption, a perceived “loss of control”, and a lack of in-person assessments and weight controls as the main contributing factors for the deterioration in AN numbers and symptomatology.ConclusionsThe COVID-19 pandemic seems to have had a deep impact on symptom severity in AN, which is mirrored by a large increase in admission rates across Europe. An increase in exercise, social media consumption, a perceived “loss of control”, and a lack of face-to-face health care seem to have contributed to this development. Further investigation is required to identify which factors may lead to the increase in incidence and deterioration of childhood and adolescent AN. Possible preventive means for the future could include educating paediatricians and health care workers about AN, regular weight assessment, and home-based treatments.

Associations of short-term exposure to air pollution and increased ambient temperature with psychiatric hospital admissions in older adults in the USA: a case–crossover study

SummaryBackgroundLittle is known about the associations between ambient environmental exposures and the risk of acute episodes of psychiatric disorders. We aimed to estimate the link between short-term exposure to atmospheric pollutants, temperature, and acute psychiatric hospital admissions in adults aged 65 years and older in the USA.MethodsFor this study, we included all people (aged ≥65 years) enrolled in the Medicare programme in the USA who had an emergency or urgent hospital admission for a psychiatric disorder recorded between Jan 31, 2000, and Dec 31, 2016. We applied a case-crossover design to study the associations between short-term exposure to air pollution (fine particulate matter [PM2·5], ozone, and nitrogen dioxide [NO2]), ambient temperature, and the risk of acute hospital admissions for depression, schizophrenia, and bipolar disorder in this population. The percentage change in the risk of hospital admission and annual absolute risk differences were estimated.FindingsFor each 5°C increase in short-term exposure to cold season temperature, the relative risk of acute hospital admission increased by 3·66% (95% CI 3·06–4·26) for depression, by 3·03% (2·04–4·02) for schizophrenia, and by 3·52% (2·38–4·68) for bipolar disorder in the US Medicare population. Increased short-term exposure to PM2·5 and NO2 was also associated with a significant increase in the risk of acute hospital admissions for psychiatric disorders. Each 5 μg/m3 increase in PM2·5 was associated with an increase in hospital admission rates of 0·62% (95% CI 0·23–1·02) for depression, 0·77% (0·11–1·44) for schizophrenia, and 1·19% (0·49–1·90) for bipolar disorder; each 5 parts per billion (ppb) increase in NO2, meanwhile, was linked to an increase in hospital admission rates of 0·35% (95% CI 0·03–0·66) for depression and 0·64% (0·20–1·08) for schizophrenia. No such associations were found with warm season temperature.InterpretationIn the US Medicare population, short-term exposure to elevated concentrations of PM2·5 and NO2 and cold season ambient temperature were significantly associated with an increased risk of hospital admissions for psychiatric disorders. Considering the increasing burden of psychiatric disorders in the US population, these findings suggest that intervening on air pollution and ambient temperature levels through stricter environmental regulations or climate mitigation could help ease the psychiatric health-care burden.

Increasing hospital admission rates for anorexia nervosa amongst young women in Australia from 1998 to 2018.

This study aims to describe the trends in community incidence, community prevalence, mortality, overnight hospital admission rates and average overnight inpatient length of stay (ALOS) for anorexia nervosa (AN) amongst young females aged 15-29 in Australia, between 1998-2018. Hospitalisation and ALOS data was obtained from the Australian Institute of Health and Welfare principal data cubes. Epidemiological data relating to community-level incidence, community-level prevalence, disability adjusted life years (DALY) and mortality were obtained from the Global Health Data Exchange. We analysed the community and hospital rates for AN in 3 female age groups, 15-19, 20-24 and 25-29. Overnight hospital female admission rates for AN have substantially increased over the past two decades, with a higher rate increase between 2008-2018 for 15-29 age groups. The largest absolute increases were seen in the 15-19 female age group. Community prevalence and DALYs increased slightly, whilst community incidence has remained relatively stable. During the study period, mortality rates and the average hospital inpatient length of stay for AN declined for females 15-29years. Overnight hospitalisation rates for AN particularly increased amongst young females (15-29) in Australia over the past decade. Less substantial increases in community incidence, community prevalence and DALYs, and declining mortality were also observed.

Hospital Admission Trends Due to Viral Infections Characterised by Skin and Mucous Membrane Lesions in the Past Two Decades in England and Wales: An Ecological Study

Objectives: This study aimed to investigate the trends in hospital admissions due to viral infections characterized by skin and mucous membrane lesions in England and Wales between 1999 and 2019. Methods: This is an ecological study using publicly available databases in England and Wales; the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. Hospital admissions data were collected for the period between April 1999 and March 2019. Hospital admissions due to viral infections characterized by skin and mucous membrane lesions were identified using the tenth version of the International Statistical Classification of Diseases system, diagnostic codes B00–B09. The trend in hospital admissions was assessed using a Poisson model. Results: Hospital admissions for different causes increased by 51.9% (from 25.67 (95% CI 25.23–26.10) in 1999 to 38.98 (95% CI 38.48–39.48) in 2019 per 100,000 persons, trend test, p < 0.01). The most prevalent viral infections characterized by skin and mucous membrane lesions hospital admissions causes were zoster (herpes zoster), varicella (chickenpox), herpesviral (herpes simplex) infections, and viral warts, which accounted for 26.9%, 23.4%, 18.7%, and 17.6%, respectively. The age group below 15 years accounted for 43.2% of the total number of admissions. Females contributed to 50.5% of the total number of admissions. Hospital admission rate in males increased by 61.1% (from 25.21 (95% CI 24.59–25.82) in 1999 to 40.60 (95% CI 39.87–41.32) in 2019 per 100,000 persons). The increase in females was 43.2% (from 26.11 (95% CI 25.49–26.72) in 1999 to 37.40 (95% CI 36.70–38.09) in 2019 per 100,000 persons). Conclusion: Our study demonstrates an evident variation in hospital admission of viral infections characterized by skin and mucous membrane lesions based on age and gender. Efforts should be directed towards vaccinating high-risk groups, particularly the elderly and females. Moreover, efforts should be focused on vaccinating the young population against varicella, particularly females who are more susceptible to acquiring the infection. Further observational and epidemiological studies are needed to identify other factors associated with increased hospital admission rates.

Impact of the COVID-19 pandemic on emergency department visits: experience of a Brazilian reference center.

ABSTRACTObjectiveTo analyze the impact of COVID-19 on emergency department metrics at a large tertiary reference hospital in Brazil.MethodsA retrospective analysis of consecutive emergency department visits, from January 1, 2020, to November 21, 2020, was performed and compared to the corresponding time frame in 2018 and 2019. The volume of visits and patients’ demographic and clinic characteristics were compared. All medical conditions were included, except confirmed cases of COVID-19.ResultsA total of 138,138 emergency department visits occurred during the study period, with a statistically significant (p<0.01) reduction by 52% compared to both 2018 and 2019. This decrease was more pronounced for pediatric visits – a drop by 71% in comparison to previous years. Regarding clinical presentation, there was a decrease of severe cases by 34.7% and 37.6%, whereas mild cases decreased by 55.2% and 56.2% when comparing 2020 to 2018 and 2019, respectively. A 30% fall in the total volume of hospital admission from emergency department patients was observed during the study period, but accompanied by a proportional increase in monthly admission rates since April 2020.ConclusionThe COVID-19 pandemic led to a 52% fall in attendance at our emergency department for other conditions, along with a proportional increase in hospital admission rates of COVID-19 patients. Healthcare providers should raise patient awareness not to delay seeking medical treatment of severe conditions that require care at the emergency department.

Impact of the Coronavirus Disease 2019 Pandemic on an Emergency Department Service: Experience at the Largest Tertiary Center in Taiwan

PurposeSevere Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) is an emerging contagious pathogen that has caused community and nosocomial infections in many countries. This study aimed to evaluate the impact of Coronavirus disease 2019 (COVID-19) on emergency services of the largest medical center in Taiwan by comparing emergency department (ED) usage, turnover, and admission rates before the COVID-19 outbreak with those during the outbreak.Materials and MethodsA retrospective cohort study was conducted in the ED of the largest tertiary medical center in Taiwan. Trends of adult, non-trauma patients who visited the ED during February–April 2019 were compared with those during February–April 2020. The number of visits, their dispositions, crowding parameters, and turnover rates were analyzed. The primary outcome was the change in ED attendance between the two periods. The secondary outcomes were changes in hospital admission rates, crowding parameters, and turnover rates.ResultsDuring the outbreak, there were decreased non-trauma ED visits by 33.45% (p < 0.001) and proportion of Taiwan Triage and Acuity Scale (TTAS) 3 patients (p=0.02), with increased admission rates by 4.7% (p < 0.001). Crowding parameters and turnover rate showed significant improvements.ConclusionComparison of periods before and during the COVID-19 outbreak showed an obvious decline in adult, non-trauma ED visits. The reduction in TTAS 3 patient visits and the increased hospital admission rates provide references for future public-health policy-making to optimise emergency medical resource allocations globally.

Trends in Emergency Department Visits and Hospital Admissions in Health Care Systems in 5 States in the First Months of the COVID-19 Pandemic in the US

As coronavirus disease 2019 (COVID-19) spread throughout the US in the early months of 2020, acute care delivery changed to accommodate an influx of patients with a highly contagious infection about which little was known. To examine trends in emergency department (ED) visits and visits that led to hospitalizations covering a 4-month period leading up to and during the COVID-19 outbreak in the US. This retrospective, observational, cross-sectional study of 24 EDs in 5 large health care systems in Colorado (n = 4), Connecticut (n = 5), Massachusetts (n = 5), New York (n = 5), and North Carolina (n = 5) examined daily ED visit and hospital admission rates from January 1 to April 30, 2020, in relation to national and the 5 states' COVID-19 case counts. Time (day) as a continuous variable. Daily counts of ED visits, hospital admissions, and COVID-19 cases. A total of 24 EDs were studied. The annual ED volume before the COVID-19 pandemic ranged from 13 000 to 115 000 visits per year; the decrease in ED visits ranged from 41.5% in Colorado to 63.5% in New York. The weeks with the most rapid rates of decrease in visits were in March 2020, which corresponded with national public health messaging about COVID-19. Hospital admission rates from the ED were stable until new COVID-19 case rates began to increase locally; the largest relative increase in admission rates was 149.0% in New York, followed by 51.7% in Massachusetts, 36.2% in Connecticut, 29.4% in Colorado, and 22.0% in North Carolina. From January through April 2020, as the COVID-19 pandemic intensified in the US, temporal associations were observed with a decrease in ED visits and an increase in hospital admission rates in 5 health care systems in 5 states. These findings suggest that practitioners and public health officials should emphasize the importance of visiting the ED during the COVID-19 pandemic for serious symptoms, illnesses, and injuries that cannot be managed in other settings.

Increased respiratory morbidity in individuals with interstitial lung abnormalities

BackgroundInterstitial lung abnormalities (ILA) are common in participants of lung cancer screening trials and broad population-based cohorts. They are associated with increased mortality, but less is known about disease specific morbidity and healthcare utilisation in individuals with ILA.MethodsWe included all participants from the screening arm of the Danish Lung Cancer Screening Trial with available baseline CT scan data (n = 1990) in this cohort study. The baseline scan was scored for the presence of ILA and patients were followed for up to 12 years. Data about all hospital admissions, primary healthcare visits and medicine prescriptions were collected from the Danish National Health Registries and used to determine the participants’ disease specific morbidity and healthcare utilisation using Cox proportional hazards models.ResultsThe 332 (16.7%) participants with ILA were more likely to be diagnosed with one of several respiratory diseases, including interstitial lung disease (HR: 4.9, 95% CI: 1.8–13.3, p = 0.008), COPD (HR: 1.7, 95% CI: 1.2–2.3, p = 0.01), pneumonia (HR: 2.0, 95% CI: 1.4–2.7, p < 0.001), lung cancer (HR: 2.7, 95% CI: 1.8–4.0, p < 0.001) and respiratory failure (HR: 1.8, 95% CI: 1.1–3.0, p = 0.03) compared with participants without ILA. These findings were confirmed by increased hospital admission rates with these diagnoses and more frequent prescriptions for inhalation medicine and antibiotics in participants with ILA.ConclusionsIndividuals with ILA are more likely to receive a diagnosis and treatment for several respiratory diseases, including interstitial lung disease, COPD, pneumonia, lung cancer and respiratory failure during long-term follow-up.

Chest computed tomography imaging utility for radiographically occult rib fractures in elderly fall-injured patients.

Previous studies demonstrate an association between rib fractures and morbidity and mortality in trauma. This relationship in low-mechanism injuries, such as ground-level fall, is less clearly defined. Furthermore, computed tomography (CT) has increased sensitivity for rib fractures compared with chest x-ray (CXR); its utility in elderly fall patients is unknown. We sought to determine whether CT-diagnosed rib fractures in elderly fall patients with a normal CXR were associated with increased in-hospital resource utilization or mortality. Retrospective analysis of emergency department patients presenting over a 3-year period. age, 65 years or older; chief complaint, including mechanical fall; and both CXR and CT obtained. We quantified rib fractures on CXR and CT and reported operating characteristics for both. Outcomes of interest included hospital admission/length of stay (LOS), intensive care unit (ICU) admission/LOS, endotracheal intubation, tube thoracostomy, locoregional anesthesia, pneumonia, in-hospital mortality. We identified 330 patients, mean age was 84 years (±SD, 9.4 years); 269 (82%) of 330 were admitted. There were 96 (29%) patients with CT-diagnosed rib fracture, 56 (17%) by CT only. Compared with CT, CXR had a sensitivity of 40% (95% confidence interval, 30-50%) and specificity of 99% (95% confidence interval, 97-100%) for rib fracture. A median of two additional radiographically occult rib fractures were identified on CT. Despite an increased hospital admission rate (91% vs. 78%) p = 0.02, there was no difference between patients with and without radiographically occult (CT+ CXR-) rib fracture(s) for: median LOS (4; interquartile range (IQR) 2-7 vs 4, IQR 2-8); p = 0.92), ICU admission (28% vs. 27%) p = 0.62, median ICU LOS (2, IQR 1-8 vs 3, IQR 1-5) p = 0.54, or in-hospital mortality (10.3% vs. 7.3%) p = 0.45. Among elderly fall patients, CT-identified rib fractures were associated with increased hospital admissions. However, there was no difference in procedural interventions, ICU admission, hospital/ICU LOS or mortality for patients with and without radiographically occult fractures. Diagnostic, level III.

Radical prostatectomy remains a challenging operation on the best of days and infectious complications from transrectal ultrasound-guided biopsies (TRUS+bx) are rising. 1 Nam RK Saskin R Lee Y et al. Increasing hospital admission rates for urological complications after transrectal ultrasound guided prostate biopsy. J Urol. 2013; 189: S12-S17https://doi.org/10.1016/j.juro.2012.11.015 Crossref Scopus (170) Google Scholar Faced with these facts, we sought to quantify the effect of a post–TRUS+bx infection on the outcomes for radical prostatectomy in these men. The study has limitations as outlined in the article and by our colleagues in the editorial based on the administrative datasets available for this work. This limited our ability to assess sexual functional outcomes, the impact of the bacteriology and treatment of the infections, the specific pathological data, and the optimum timing for radical prostatectomy for men who have suffered from a post–TRUS+bx infection. These remain unanswered questions that require further investigation to build on our understanding of the postinfection risks.

A protocol for the process evaluation of a multi-centre randomised trial to compare the effectiveness of geriatrician-led admission avoidance hospital at home versus inpatient admission

BackgroundAttempts to design services to support the delivery of healthcare closer to home have taken various forms as countries respond to an increase in hospital admission rates for older people, who are at risk of hospital-acquired morbidity, prolonged lengths of stay and readmission. Evidence to support the development of these services is limited. We are conducting a process evaluation, alongside a UK multi-site randomised trial, to understand the contexts and practices of implementing geriatrician-led admission avoidance hospital at home services and to explore ways that the intervention might be effective, under what conditions, for whom, and how it differs from inpatient care.MethodsWe are interviewing patients and their caregivers, from sites that are purposively sampled from participating National Health Service (NHS) trusts across the UK. We are also visiting sites to observe local processes and discuss the establishment and running of services with a range of multidisciplinary staff, managers, commissioners, primary care and social services representatives. We aim to interview approximately 36 patients and their caregivers with experience of hospital at home or inpatient services; 12 at each of three sites. We will use a content analysis approach to explore data across participants, services and sites.DiscussionThis process evaluation will enable evaluation of implementation processes prior to knowing trial outcomes. We encompass domains of reach, delivery, change, context and response to the intervention by patients, their carers, health professionals and the health system.Trial registrationISRCTN60477865.

An Assessment of Potential Unintended Consequences Following a National Antimicrobial Stewardship Program in England: An Interrupted Time Series Analysis.

The "Quality Premium" (QP) introduced in England in 2015 aimed to financially reward local healthcare commissioners for targeted reductions in primary care antibiotic prescribing. We aimed to evaluate possible unintended clinical outcomes related to this QP. Using Clinical Practice Research Datalink and Hospital Episode Statistics datasets, we examined general practitioner (GP) consultations (visits) and emergency hospital admissions related to a series of predefined conditions of unintended consequences of reduced prescribing. Monthly age- and sex-standardized rates were calculated using a direct method of standardization. We used segmented regression analysis of interrupted time series to evaluate the impact of the QP on seasonally adjusted outcome rates. We identified 27334 GP consultations and >5 million emergency hospital admissions with predefined conditions. There was no evidence that the QP was associated with changes in GP consultation and hospital admission rates for the selected conditions combined. However, when each condition was considered separately, a significant increase in hospital admission rates was noted for quinsy, and significant decreases were seen for hospital-acquired pneumonia, scarlet fever, pyelonephritis, and complicated urinary tract conditions. A significant decrease in GP consultation rates was estimated for empyema and scarlet fever. No significant changes were observed for other conditions. Findings from this study show that overall there was no significant association between the intervention and unintended clinical consequences, with the exception of a few specific conditions, most of which could be explained through other parallel policy changes or should be interpreted with caution due to small numbers.

Assessment of the Utility of Ordering a Troponin in Low- and Intermediate-Risk Patients Presenting to the Emergency Department with Supraventricular Tachycardia: A Retrospective Chart Review

BackgroundA troponin assay is commonly sent for patients presenting to emergency departments (EDs) with supraventricular tachycardia (SVT). Multiple studies suggest that elevated troponin levels do not predict coronary artery disease in these patients. Patients with elevated troponins are more likely to have additional cardiac testing, which can lead to increased health care costs and unnecessary invasive procedures. ObjectiveOur objective was to evaluate low- to intermediate-risk patients (HEART [history, electrocardiography, age, risk factors and troponin] Score 1–6) presenting to the ED with SVT. Our hypothesis was that an elevated troponin would not predict major adverse cardiac events (MACE), but would be associated with increased hospital admission rates and lengths of stay. MethodsThis was a retrospective cohort study of adult patients who presented with SVT to a large, urban, academic hospital ED over 4 years who had a troponin result. A total of 46 patients were included in the study. ResultsPatients with a positive troponin (>0.05 ng/mL) had a hospital admission rate of 86% versus 21% for patients with negative troponin (p = 0.006); rate of cardiology consult of 86% versus 21% (p < 0.001); and a mean total length of stay of 4157 min versus 1347 min (p = 0.04). At 3 months, none of the patients with a positive troponin had an MACE, death from any cause, or positive results of cardiac testing. ConclusionsPatients with a positive troponin result had significantly more admissions, cardiology consults, and longer hospital stays. These patients did not have an increased prevalence of MACE.
